“…Arabidopsis mutants in ribosomal proteins exhibit a large range of developmental phenotypes with extreme abnormalities, including embryonic lethality, suggesting that ribosomes also have specific functions regulating the expression of developmental genes (Van Lijsebettens et al, 1994;Degenhardt and Bonham-Smith, 2008;Byrne, 2009;Horiguchi et al, 2011Horiguchi et al, , 2012Szakonyi and Byrne, 2011). Furthermore, it has been recently demonstrated that ribosomal proteins control auxinmediated developmental programs by translational regulation of auxin response factors (Rosado et al, 2012). In addition, the characterization of single, double, and, in certain cases, triple mutants as well as complementation by paralog genes have demonstrated full, partial, and no redundancy between members of ribosomal protein families (Briggs et al, 2006;Guo and Chen, 2008;Guo et al, 2011;Horiguchi et al, 2011;Stirnberg et al, 2012).…”
